  4	  Say Y here to enable external connector class (extcon) support.
  5	  This allows monitoring external connectors by userspace
  6	  via sysfs and uevent and supports external connectors with
  7	  multiple states; i.e., an extcon that may have multiple
  8	  cables attached. For example, an external connector of a device
  9	  may be used to connect an HDMI cable and a AC adaptor, and to
 10	  host USB ports. Many of 30-pin connectors including PDMI are
 11	  also good examples.
